拉延修邊模 的英文怎麼說
中文拼音 [lāyánxiūbiānmó]
拉延修邊模
英文
drawing and trimming die-
In this thesis it was proposed to simulate the drawing, trimming, flanging by using error - adjustment method. the initial trimming lines would be adjusted and optimized in the computer by adjusting error. if the shape error between the flanging boundary line and the target is larger than prescribed, the redundant area is subtracted from the initial blank by some amount of volume along the deformation path, and the insufficient volumes are added to the initial blank by the same amount
本文提出,利用基於變形路徑的誤差修正法( error - adjustment ) ,結合cae技術將對初始修邊線的調試過程在計算機中進行模擬(包括拉延、修邊、翻邊、整形等)計算,通過控制翻邊后零件成型邊界與實際目標輪廓之間的尺寸誤差來優化修邊線,如果初始切邊、翻邊后的輪廓與目標體的邊界存在較大偏差,則初始切邊輪廓中多餘部分單元將沿其變形路徑以相同體積量被切除,不足部分則沿其變形路徑以相同體積進行補償。So how to determine the trimming shape and dimension for exact flanging is very important for reducing the period of producing trimming mould and saving the cost. simultaneously it is a difficult problem in whole mould manufacture. several common methods of calculating the cutting contour were discussed in this thesis
拉延後如何確定修邊線的尺寸和形狀,使翻邊后突緣輪廓正好達到零件所需翻邊高度,對于縮短模具製造周期,減少生產成本都具有重要意義,同時也是整個模具行業亟待解決的一大難題。
